# JSON Lines をストリームする { #stream-json-lines }

データのシーケンスを**「ストリーム」**で送りたい場合、**JSON Lines** を使って実現できます。

FastAPI 0.134.0 で追加されました。

## ストリームとは { #what-is-a-stream }

データを**ストリーミング**するとは、アイテムの全シーケンスが用意できるのを待たずに、アプリがデータアイテムの送信をクライアントに対して開始することを意味します。

つまり、最初のアイテムを送信し、クライアントはそれを受け取って処理を始めます。その間に、次のアイテムをまだ生成しているかもしれません。
